write_uint16
write_uint16(f, n, [endian=])Input: f, n, endian · Output: no output
What it is
Writes n (number) to f (file handle, opened writable/appendable) as an unsigned 16-bit integer. endian (string, optional, default "little", or "big") selects byte order.
Overloads
One call shape — this function is not overloaded.

Examples
From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.
f = fopen("records.bin", "wb")
write_double(f, 0.0)
write_uint16(f, 12)
write_double(f, 0.5)
write_uint16(f, 15)
close(f)
fields = [["t", "f64"], ["ch", "u16"]]
g = fopen("records.bin", "rb")
one = read_struct(g, fields)
close(g)
print(one.t) # 0
print(one.ch) # 12
h = fopen("records.bin", "rb")
tbl = read_structs(h, fields, 2)
close(h)
print(nrow(tbl)) # 2
print(tbl.ch) # [12, 15]
output
0 12 2 [12, 15]
